摘要
URA编码孔径成像是X射线成像的一项新技术.它不但提高了信噪比,而且具有层析分辨能力.本文详细论述了URA编码孔径的层析成像原理,并提供了一种改善层析成像质量的叠代方法.并应用迭代方法成功地进行了计算机模拟实验.
The coded aperture imaging using URA pattern is a new technique for X-ray imaging. It can improve S/N, and has tomographio capability. In this paper, we describe the principle of tomographioal imaging using URA coded aperture in detail, and provide a iterative method for improving tomographioal imaging. The computer simulation using iterative method has been successfully performed.
